I do not want to get blamed from my friends by urging them to buy and the price keeps dropping, I could lose my friends if I do this, maybe to my enemy I can urge them to do so, you can promote Bitcoin but when it comes to buying you should give them the advantages and disadvantages.
What do you mean by that?
Before you urge them to buy or invest on Bitcoin and other cryptocurrencies, explain to them first what Bitcoin is, what can affect the price of it? It is safe or not to invest right now? Something like that. That is the misconception of people that want to invite their friends, they are saying that they should invest but they are not explaining first what it is. Talk to them first, tell them what you know about it and they will be the one deciding if they should buy or not, don't decide for them, let them so they can learn.
